Why does IR look bluish to cameras? That seems like the wrong end of the spectrum to detect.

@chjara we decided IR was red for no particular reason, IR has no color

@Stellar Yes, but infrared, as its name indicates, is right under red. So it seems strange to me that it'd get some component of blue in a digital camera.

@Stellar To be clear I'm talking about like when you put an IR remote to a phone camera, it shows up kinda purpleish.

@chjara maybe for some reason the blue filter can't reject ir while the others do?

@chjara on a unmodified camera its blue because of the infrared filter that’s on the light captor

@chjara when you rip it off, infrared shows as pink. (salmon,) i’ve tried

@chjara i’d guess the colour filters in front of the ccd pixels are not optimised for their IR rejection (normally you put an additional IR filter in front of the camera)

@Paradox @chjara sooo, literally just spitballing here
but i suspect it's because the blue filter is what's leaking the infrared, assuming digital here
even then, digital cameras are supposed to have an infrared filter /shrugs/
probably a question more for the semiconductor nerds than the photographers ^^'
